# Q3, W5: February 22-26 Geometry

Teacher Kristin Andreason Geometry Honors 8 February 22-26 Unit 5: Quadrilaterals
Standard(s) Taught

MAFS.912.G-CO.3.11:  Prove theorems about parallelograms; use theorems about parallelograms to solve problems. (Theorems include: opposite sides are congruent, opposite angles are congruent, the diagonals of a parallelogram bisect each other, and conversely, rectangles are parallelograms with congruent diagonals.)

Learning Targets and Learning Criteria

apply theorems, postulates, or definitions to prove theorems about parallelograms (including rhombus, rectangle, square), including:

a)  Prove opposite sides of a parallelogram are congruent;

b)  Prove opposite angles of a parallelogram are congruent;

c)  Prove the diagonals of a parallelogram bisect each other;

d)  Prove that rectangles are parallelograms with congruent diagonals.

•  Use properties of parallelograms, NOT assumptions, to correctly identify figures.
